| Summary | 0002170: Improve software I2C handling if line is stuck | ||||
| Description | If a software driven I2C port (i2c-gpio) is stuck (e.g. if a transmission was interrupted while the device held the SDA line low), the bus can not be used. Add a check for free bus and if bus is busy, output some clocks until SDA is let free and then issue a STOP condition on the bus to reset the sending device. Then we can start transmitting. | ||||
